Red Storm. Add stub functions to ompi_config_bottom.h when they are around * Add protection for a bunch of #include <netinet/in.h>s * Fix up the Portals BTL so that it compiles on Red Storm and has the right mojo for initialization on Red Storm * Add some important comments to ompi_check_package and mvapi configures * Add support for platforms without getpwuid() (aka, Red Storm). This commit was SVN r6478.

* - potentially override malloc, free, etc. for memory debugging
|

* - set ompi_building code to import all OMPI interfaces (windows)

|
* If OMPI_BUILDING is 0, ompi_config.h will:
|
|
* - set configuration #defines

* - define the fortran complex types
|
|
* - set the ompi_building code to export all the interfaces
|
|
* (unless OMPI_BUILDING_WIN_DSO is set to 1) (windows)
|
|
*
|

* If OMPI_BUILDING_WIN_DSO is 1, ompi_config.h will:
|
|
* - configure the OMPI_DECLSPEC defines to assume we are building a
|
|
* dynamic shared object for a component on Windows. This will set
|
|
* all the import/export flags appropriately.
|
|
*
|
|
* If OMPI_BUILDING_WIN_DSO is 0 (or unset), ompi_config.h will:
|
